Here I show you the teardown of just another LSPA9 housing.
I opened it with my door of course 😂

After I de-soldered the sub PCB I can connect some thin wires to the connection points I need to flash the device.
The sub PCB is the new one WL2S with the Wi-Fi chip LN882H.
This chip needs to flash a permanent ground connection at the pin A9, you can also find this point for soldering on the sub PCB.
The following description to flash this chip works very well.

Used the described tool to flash the device with my Windows machine.

But I need to screw down the serial speed to get a working connection.

Here is a working configuration for the pins:

"3": "Btn;0",
"7": "BL0937CF1;0",
"10": "Rel_n;1",
"11": "Rel;0",
"12": "BL0937CF;0",
"19": "BL0937SEL;0"

Pin 10 normally is used and configured as the Wi-Fi LED.
